All releases of filtergen

Release Notes: The example in the filter_syntax man page was fixed, as was a 64-bit compilation warning in the filter.c netmask calculation. A "-F [policy]" flush option was added, and better feedback was provided for parse errors.

Release Notes: This version fixes the iptables sub-chains (and partially fixes the same for ipchains), includes log text support, and provides an RPM spec, init script, and associated Makefile. More complete examples were included, and some small bugs were fixed.

Release Notes: A minor Makefile issue was fixed. All protocols in /etc/services and numeric
protocols specified by number are now supported. The "-m" option was added to
force lookup of IP addresses and port numbers.

Release Notes: Host-mode and router-mode were added, with syntax
and command-line options to specify them. Straight
packet forwarding now works properly. A small
change was made to the state model so that
established rules go at the head of the chain. A
"lightweight state" mode was added. Several bugs
were fixed. The iptables driver was expanded and
the ipchains driver was cleaned up. Some new
documentation was added.

Release Notes: Disabling negation of conjunctions ("or"s, aka brace-grouping), a new "no skeleton" option, fixes for a couple of segfaults/aborts where input filter is invalid, allowing literal +, ", and _ signs in input, and addition of sub-groups (where supported, large sub-sections can be moved out-of-line to improve performance).
